摘要：

A notable effect of the retained heat after the fiction stir welding (FSW) of Cu was studied by the application of additional liquid CO2 cooling. The adjustment of the welding parameters made it possible to conduct the FSW processes, but the cooling rate of the joint was not sufficiently changed due to the existence of the post-annealing effect. However, the accelerated cooling can reduce the post-annealing effect and provide an ultrafine grain structure with a high dislocation density in the stir zone, and a joint with mechanical properties better than the base metal level was achieved.
